One of the man’s other daughters called 911 around 2:30 a.m., saying her dad “found a man under her sister’s bed,” according to KPRC. Authorities now tell the station that the 16-year-old girl whose bed the teen was hiding under knew the 17-year-old boy and let him into the house.

The father was taken to a hospital for tests after complaining of feeling ill, an officer with the Harris County Sheriff’s Office told HLN.

Authorities say an investigation is underway, but they have not said whether they will press charges at this time.
